United States atentO "ce GLAZIERS PGINT DRIVER Chester K. Judd, Jr.,Bristol, Conn., assignor to The Fletcher-Terry Company, Forestville,Conn., a corporation of Connecticut Application November 28, 1955,Serial No. 549,251 Claims. (Cl. 1-44) This invention relates to aglaziers point driver and more particularly to a hand operated devicefor dispensing and driving glaziers points into a window sash or thelike to hold panes of glass therein.

An object of the present invention is to provide such a device Which ishighly efiicient in its operation and which can be economically producedin large quantities.

A further object of this invention is to provide such a device which iseasy to use and to refill with points when necessary.

Further objects and advantages of this invention will be more clearlyunderstood from the following description and the accompanying drawingsin which:

Fig. l is a plan view of a glaziers. point driver embodying my presentinvention.

Fig. 2 is an enlarged sectional end view thereof on line 22 of Fig. 3,but with the point magazine removed.

Fig. 8 is an isometric view of the combined point driver and returnspring member.

Fig. 9 is a plan view of the anchoring member.

Fig. 10 is a plan view of the carrier member.

Fig. 11 is a bottom view of said carrier member.

As illustrated in the drawings, my improved device includes a frame 5which is preferably formed of round wire and includes an upwardlyinclined U-shaped handle portion 6 and a base portion 7; the said baseportion consisting of a pair of spaced parallel prongs 8-8 which projectforwardly from the portion 6.

An anchoring member 9 extends across said prongs and consists of anelongated bar 10 having inverted U- shaped end portions 11-11 whichextend over the prongs and are preferably spot welded thereto, asindicated at 12-12, to secure the said anchoring member to the prongs.The bottom surface of said member is substantially on a plane with thebottom surfaces of the prongs, and the central portion thereof is bentupwardly, as at 13, to provide a channel thereunder and has an opening14 therein. The anchoring member 9 carries a combined point driver andreturn spring which is constructed of fiat spring stock and includes adriver 15, that is riveted to the underside of the said portion 13, andan inverted U-shaped return spring portion 16, one leg of which extendsupwardly through the said opening 14 and the other leg having a free endportion 17 bent forwardly therefrom.

The said anchoring member 9'is disposed rearwardly of the free endportions of the prongs 8-8, and a carrier member 18 extends across saidend portions of the prongs. The said carrier member consists of an upperFatented dart. 2Q, 1859 plate 19 having inverted U-shaped end portions20-20, in which slidably fit the end portions of the prongs 8-8, andlower plate portions 21-21 which extend inwardly from the U-shapedportions and under the said prongs and the central portion of said upperplate 19, as clearly illustrated in Fig. 2. The central portion of saidupper plate is bent upwardly, as at 22, to provide a centrally locatedpassage through the carrier member which is in alignment with thechannel that is formed under the upwardly bent portion 13 of thestationary anchoring member 9. As shown in Fig. 11, one of the lowerplate portions 21 of the carrier member 18 has an extension 23 whichprojects into a notch in the opposite plate portion 21 to strengthen thebottom of said carrier member.

The driver 15 is secured against the bottom of the raised portion 13 andextends forwardly therefrom into the said passage 24, as clearlyillustrated in Fig. 5. The front portion of the said driver has aV-notch 25 therein to conform with the shape of the glaziers points thatare used with said device.

The upwardly bent portion 22 (Fig. 6) of the carrier member has anupwardly extending lip 26 which provides an abutment for anchoring thefree end 17 of the return spring portion 16, and the said raised portionalso has a hole 27 therein, shaped like the glaziers points, butslightly larger, which is adapted to receive the lower end of a stack ofpoints 28 which are adhered together by a suitable adhesive that isadapted to release only the bottom point from the stack as it is beingdriven by the device.

The upper plate 19 (Fig. 2) and the lower plates 21- 21 of the carriermember are secured together by a pair of vertical posts 29 29 whichextend upwardly from the carrier member 18, at opposite sides of theportion 22, and provide a support for a tubular magazine 30 which has acentral portion 31, that conforms to the shape of the points, andtubular side portions 3232 extending therefrom which fit over the saidposts 2929 so that the said magazine is slidable thereon and may beremoved by raising it off said posts.

In order to force the said stack of points downwardly, I provide aninverted U-shaped spring member 33 having one end thereof preferablyanchored upon the anchoring member 9 by a rivet 34. Its opposite end isfreely movable and extends downwardly into the magazine 31) andhas aloop 35 at its end which engages the top of the stack of points.

The carrier member 18 has slots 36--36 in its opposite sides whichreceive projections 37-37 extending from the prongs 8-8 that engage theends of said slots and slidably retain the said carrier member on theprongs.

In the use and operation of my improved device, the

stack of points 28 is first placed in the tubular magazine 30 so thatthe bottom of said stack extends into the'hole' 27 and rests upon thebottom of the passage 24, directly in front of the driver 15 and partlywithin the notch 25 therein. The free end of the spring member 33 isthen inserted into the magazine and allowed to press upon the top of thestack of points and the device is ready for use.

When it is desired to drive the said points into a window sash 38, orthe like, the device is simply held by the handle 5 and the carriermember 18 is placed on the surface of the glass and against the side ofthe sash. The handle 5 is then forced towards the sash and this willmove the member 9 and driver 15 forwardly relatively to the carriermember 18 causing it to pick up the bottom point in the stack 28 withinthe notch 25 and force said point forwardly, through the passage 24 andinto the sash, as illustrated in Fig. 6. The device is then moved awayfrom the sash and the spring 16 will return it to its normal positionshown in Fig. 5.
